Comparisons between Plant and Animal Stem Cells Regarding Regeneration Potential and Application. Int J Mol Sci 2023; 24:ijms24054392. [PMID: 36901821 PMCID: PMC10002278 DOI: 10.3390/ijms24054392] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 02/16/2023] [Accepted: 02/21/2023] [Indexed: 02/25/2023] Open
Abstract
Regeneration refers to the process by which organisms repair and replace lost tissues and organs. Regeneration is widespread in plants and animals; however, the regeneration capabilities of different species vary greatly. Stem cells form the basis for animal and plant regeneration. The essential developmental processes of animals and plants involve totipotent stem cells (fertilized eggs), which develop into pluripotent stem cells and unipotent stem cells. Stem cells and their metabolites are widely used in agriculture, animal husbandry, environmental protection, and regenerative medicine. In this review, we discuss the similarities and differences in animal and plant tissue regeneration, as well as the signaling pathways and key genes involved in the regulation of regeneration, to provide ideas for practical applications in agriculture and human organ regeneration and to expand the application of regeneration technology in the future.

Genome of the sea anemone Exaiptasia pallida and transcriptome profiles during tentacle regeneration. Front Cell Dev Biol 2022; 10:900321.

Abstract
Cnidarians including sea anemones, corals, hydra, and jellyfishes are a group of animals well known for their regeneration capacity. However, how non-coding RNAs such as microRNAs (also known as miRNAs) contribute to cnidarian tissue regeneration is poorly understood. Here, we sequenced and assembled the genome of the sea anemone Exaiptasia pallida collected in Hong Kong waters. The assembled genome size of E. pallida is 229.21 Mb with a scaffold N50 of 10.58 Mb and BUSCO completeness of 91.1%, representing a significantly improved genome assembly of this species. The organization of ANTP-class homeobox genes in this anthozoan further supported the previous findings in jellyfishes, where most of these genes are mainly located on three scaffolds. Tentacles of E. pallida were excised, and both mRNA and miRNA were sequenced at 9 time points (0 h, 6 h, 12 h, 18 h, 1 day, 2, 3, 6, and 8 days) from regenerating tentacles. In addition to the Wnt signaling pathway and homeobox genes that are shown to be likely involved in tissue regeneration as in other cnidarians, we have shown that GLWamide neuropeptides, and for the first time sesquiterpenoid pathway genes could potentially be involved in the late phase of cnidarian tissue regeneration. The established sea anemone model will be useful for further investigation of biology and evolution in, and the effect of climate change on this important group of animals.

[PMID: 35892951 PMCID: PMC9332576 DOI: 10.3390/biology11081095] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 06/21/2022] [Accepted: 06/28/2022] [Indexed: 11/20/2022]
Abstract
Most species of the class Holothuroidea are able to regenerate most of their internal organs following a typical evisceration process, which is a unique mechanism that allows sea cucumbers to survive in adverse environments. In this review, we compare autotomy among different type of sea cucumber and summarize the histocytological events that occur during the five stages of intestinal regeneration. Multiple cytological activities, such as apoptosis and dedifferentiation, take place during wound healing and anlage formation. Many studies have focused on the molecular regulation mechanisms that underlie regeneration, and herein we describe the techniques that have been used as well as the development-related signaling pathways and key genes that are significantly expressed during intestinal regeneration. Future analyses of the underlying mechanisms responsible for intestinal regeneration should include mapping at the single-cell level. Studies of visceral regeneration in echinoderms provide a unique perspective for understanding whole-body regeneration or appendage regeneration.

Abstract
The aim of this article is to analyze the genetic and immunological mechanisms of the development of fracture consolidation disorders at the present scientific stage.Materials and methods. The search for literary sources was carried out in the open electronic databases of scientific literature PubMed and eLIBRARY. Search depth – 10 years.Results. The review analyzes the literature data on the current state of the study of the molecular genetic mechanisms of reparative regeneration including the development of fracture consolidation disorders. The mechanisms of the most important links of pathogenesis which most often lead to various violations of the processes of bone tissue repair are considered.Conclusion. The process of bone tissue repair is multifaceted, and many factors are involved in its implementation, however, we would like to note that the leading role in the course of reparative regeneration is played by a personalized genetically programmed response to this pathological condition. Nevertheless, despite the undeniable progress of modern medicine in studying the processes of bone recovery after a fracture, there are still many “white” spots in this issue, which dictates the need for further comprehensive study in order to effectively treat patients with impaired consolidation.

Abstract
Holothurians, or sea cucumbers, belong to the phylum Echinodermata. They show good regenerative abilities. The present review provides an analysis of available data on the molecular aspects of regeneration mechanisms in holothurians. The genes and signaling pathways activated during the asexual reproduction and the formation of the anterior and posterior parts of the body, as well as the molecular mechanisms that provide regeneration of the nervous and digestive systems, are considered here. Damage causes a strong stress response, the signs of which are recorded even at late regeneration stages. In holothurian tissues, the concentrations of reactive oxygen species and antioxidant enzymes increase. Furthermore, the cellular and humoral components of the immune system are activated. Extracellular matrix remodeling and Wnt signaling play a major role in the regeneration in holothurians. All available morphological and molecular data show that the dedifferentiation of specialized cells in the remnant of the organ and the epithelial morphogenesis constitute the basis of regeneration in holothurians. However, depending on the type of damage, the mechanisms of regeneration may differ significantly in the spatial organization of regeneration process, the involvement of different cell types, and the depth of reprogramming of their genome (dedifferentiation or transdifferentiation).

Abstract
The diversity of mechanisms and capacity for regeneration across the Metazoa present an intriguing challenge in evolutionary biology, impacting on the burgeoning field of regenerative medicine. Broad taxonomic sampling is essential to improve our understanding of regeneration, and studies outside of the traditional model organisms have proved extremely informative. Within the historically understudied Spiralia, the Annelida have an impressive variety of tractable regenerative systems. The biomeralizing, blastema-less regeneration of the head appendage (operculum) of the serpulid polychaete keelworm Spirobranchus (formerly Pomatoceros) lamarcki is one such system. To profile potential regulatory mechanisms, we classified the homeobox gene content of opercular regeneration transcriptomes. As a result of retrieving several difficult-to-classify homeobox sequences, we performed an extensive search and phylogenetic analysis of the TALE and PRD-class homeobox gene content of a broad selection of lophotrochozoan genomes. These analyses contribute to our increasing understanding of the diversity, taxonomic extent, rapid evolution, and radical flexibility of these recently discovered homeobox gene radiations. Our expansion and integration of previous nomenclature systems helps to clarify their cryptic orthology. We also describe an unusual divergent S. lamarcki Antp gene, a previously unclassified lophotrochozoan orphan gene family (Lopx), and a number of novel Nk class orphan genes. The expression and potential involvement of many of these lineage- and clade-restricted homeobox genes in S. lamarcki operculum regeneration provides an example of diversity in regenerative mechanisms, as well as significantly improving our understanding of homeobox gene evolution.
